Aurélio Buarque de Holanda Ferreira

Aurélio Buarque de Holanda Ferreira (May 3, 1910 – February 28, 1989) was a Brazilian lexicographer, philologist, translator, and writer, best known for editing the ''Novo Dicionário da Língua Portuguesa'', a major dictionary of the Portuguese language.

His family name was originally spelled Hollanda, but was changed to Holanda, presumably to follow the Portuguese spelling reform of 1943. Provided by Wikipedia
